From the introduction:
Teenage girl develops dangerous powers.
In 1983 Americans are scared to death of Soviet attack and nuclear war. To combat the Soviet threat a joint team of CIA and military personnel has been developing a new kind of weapon in a secret test lab. This weapon is Iris Lindstrom, a teenage girl with newfound psionic abilities. The team, headed by brilliant psychologist Dr. Sands, is trying to research, magnify, control and ultimately duplicate Iris’ power. In practice, this means endless tests in a sterile environment. The lab complex itself is hidden under a remote farm in Iowa, surrounded by an endless plateau of cornfields.
